Well, then it won't be on the table anymore. You might be right that they roll it back (almost certainly they will if this actually leads to professional Whites tribing up,) but for the moment it's not a bad way to think. Even if that eventually happens, four years could be a good amount of time to leverage the rule to get a bunch of competent Whites working together at the exclusion of shitskins.
Edit: No, seriously. Don't just downvote and move on because the thought is uncomfortable.
Biden was the instrument to rug-pull Trump's first term, what makes you think they won't cheat someone else in in four years to do the same again?
Don't be a nigger. Use your head for something besides a burnt-cheetoh rack.
